Axle ratio did not affect the radiator usage with one (unverified) exception. In the April 1 1969 revision of the dealer ordering information, it states that Positraction Rear Axles: Ratios 3.73 or 4.10 without Special Performance Package (Z28) or 396 engine "also includes HD radiator" and the MSRP is $56.90. This means that a SS350 (or L65 or 307) with 3.73 or 4.10 gears would automatically get the V01 radiator. This would also apply to COPO 427 cars (and the higher price showed up on some later COPO window stickers), but they already received a 4 core radiator as part of the COPO package.
